Priority: medium
Bug ID: 76252
Assignee: [email protected]
Summary: Dynamic loading/unloading of opengl32.dll results in a
deadlock
Severity: major
Classification: Unclassified
OS: Windows (All)
Reporter: [email protected]
Hardware: x86-64 (AMD64)
Status: NEW
Version: 10.1
Component: Mesa core
Product: Mesa
I'm using llvmpipe for software rendering under windows. To switch easily
between hardware and software rendering I loaded the opengl32.dll dynamically.
Unloading the hardware OpenGL library works fine, but unloading mesa results in
a deadlock.
Stacktrace:
opengl32.dll!lp_rast_destroy(lp_rasterizer * rast) Line 948 C

Setting LP_NUM_THREADS=0 workarounds this problem.
