Hi,

attaching a STC for the issue I reported last week about all large
binaries crashing with exception C0000005. The test case is a shell
script that generates and compiles a bunch of c files, and finally
links them together to one large exe file. Using the constants in the
file (NUM_1MB=263, NUM_1K=548, NUM_1B=545) generates a binary that is
263615343 bytes for me (using gcc 4.3.4 20090804 (release) 1), and
which crashes when started. Reducing NUM_1B by one generates a binary
that is also 263615343 bytes, but works. While they have the same
size, they are very different internally - "objdump -t" shows very
small differences between NUM1B=543 and 544, but very large
differences between 544 and 545. Anyone here who's familiar with how
exe files are handled that could take a look at this?

BR
Magnus
